Thanks @infinitelearning for updating me about mangosteem! I see that as mangosteem is on blockchain one can directly land on the Steemit profile when clicking on user's chat ID. But I'd appreciate if instead of leading the user to some other website, some chat feature can be integrated in the Steemit platform itself.

When using websites like mangosteem, the first question came to my mind was that if this one is an independent chat platform on blockchain then why do it's user IDs are linked to Steemit website? Can't there be a way to edit my preference if I want to go to Busy or ChainBB or any other website? Other aspect is I'm required to trust the Steem Connect tool to log into this chat. I think all these can be solved if Steemit development team can integrate such a tool in their own website. But yeah, thanks to @mynameisbrian for showing a way to take things forward.

Here is a small tip! being posted for you @infinitelearning, hope you won't mind that.
